Abstract

Abstract Rearing black soldier fly is an efficient way to dispose of organic waste by converting them into protein-rich feed to substitute animal- and plant-based sources in animal feeds. The objective of this study was to determine the optimal inclusion level of black soldier fly larvae meal (BSFLM) as a substitute for soybean meal (SBM) in broiler diets and evaluate the impact on growth and carcass characteristics. Five isonitrogenous diets (D) (20% crude protein, CP) and isocaloric (3,200 Kcal/kg) were formulated such that BSFLM substituted SBM at 0% (control, D1), 25% (D2), 50% (D3), 75% (D4), and 100% (D5) on a protein basis. A total of 270 broilers (Cobb 500) were randomly assigned to the five treatments in triplicate per diet. BSFLM displayed higher fat content (44.84 ± 0.08%). Average daily feed intake (ADFI) decreased with an increase in BSFLM in the diets (p = 0.004). However, overall weight (OW) was high (1,296.97 ± 46.19 g) on 100% substitution of SBM with BSFLM (D5). Breast fat content averaged 6.06 ± 0.97 g for D1 and 15.30 ± 0.5 g for D5. This study has demonstrated that BSFLM can partially or wholly replace conventional SBM in the diet of broiler chicken.

粪污泥废弃物处理产物黑虻幼虫饲料对肉鸡生长性能和胴体特性的影响

饲养黑兵蝇是一种有效的处理有机废物的方法，将其转化为富含蛋白质的饲料，以替代动物饲料中的动物和植物源。本试验旨在确定黑虻幼虫粕(BSFLM)替代豆粕(SBM)在肉鸡饲粮中的最佳添加水平，并评价其对肉鸡生长和胴体特性的影响。试验配制了5种等氮饲粮(D)(20%粗蛋白质，CP)和等热量饲粮(3200 Kcal/kg)，以BSFLM代替SBM，蛋白质含量分别为0%(对照，D1)、25% (D2)、50% (D3)、75% (D4)和100% (D5)。选取270只肉仔鸡(Cobb 500)，随机分为5个处理，每个饲粮3个重复。BSFLM脂肪含量较高(44.84±0.08%)。平均日采食量(ADFI)随饲料中BSFLM的增加而降低(p = 0.004)。然而，当BSFLM 100%替代SBM时，总重量(OW)很高(1,296.97±46.19 g) (D5)。D1和D5的乳腺脂肪含量分别为6.06±0.97 g和15.30±0.5 g。本研究表明，BSFLM可部分或全部替代肉鸡饲粮中的传统SBM。
